How to spend the winter in northern hydrangeas (how to care for outdoor hydrangeas before winter)

Can hydrangeas winter outside?

Hydrangea is a cold-resistant plant that can tolerate temperatures of 5°C . It can spend the winter outdoors in the north . In the south, the winter is also warm, so it can be placed outdoors and spend the winter safely. In the north, the outdoor temperature is below zero in winter, so it should be moved indoors in time for management.

For potted hydrangeas, because they stop growing in winter and enter a dormant period , you should reduce the amount of watering. You should also reduce the amount of fertilizer to avoid excessive nutrition due to excessive fertilizer. You should also pay attention to pests and diseases.

If it is a ground-planted hydrangea, when it is wintering, you need to cover the roots of the ground-planted seedlings with more soil to protect the root system and take good warming measures . Especially for flower lovers who plant hydrangeas in the north, you can dig up the soil in spring and then prune the branches .

How to grow hydrangea in winter in the north

temperature

Hydrangea is a plant that likes to grow in a warm environment. Therefore, it has high temperature requirements. The temperature is low in winter. Hydrangea can be grown indoors, but the temperature needs to be kept at around 20 degrees .

Hydrangeas prefer shade, but the temperature difference is large in winter, so the temperature at night should not be lower than 10 degrees. The temperature during the day is relatively high, so a constant temperature is sufficient.

Watering

In winter, the temperature is low and hydrangeas enter a dormant period and stop growing. Therefore, when caring for them, the amount of watering must be reduced and they can be watered once every half a month . Water thoroughly and keep the soil in the pot moist. Water when the soil is half moist.

Fertilization

In winter, you can reduce the use of fertilizer for hydrangeas because they are already in a dormant period , so using fertilizer will easily lead to excess nutrition. The branches and leaves of the flowers will wither and rot. Fertilization requires the use of diluted fertilizers. It is best to use nitrogen fertilizers, and thin fertilizers are acceptable.

Pruning and keeping warm

We can trim the rotten leaves and roots, and then cover the hydrangea with a plastic bag to keep it warm. Because the plastic bag is airtight and ventilated, it prevents cold air from entering.

Pest Control

The temperature is low in winter, but hydrangeas can also have disease problems. Therefore, pesticide spraying is needed to prevent the occurrence of diseases. If a disease is found, it needs to be dealt with in time.
